Description

Technical Field

[0001] The utility model relates to the technical field of logistics and transportation mechanical equipment, in particular to a lifting and transferring device and a conveying line. Background Art

[0002] In the field of industrial production and logistics, conveyors are important tools for achieving efficient material transportation. However, when industrial products or logistics goods need to change direction during transportation, traditional conveyors often face challenges. To solve this problem, special measures or reliance on manual labor are usually required, which reduces overall efficiency and increases costs.

[0003] A lifting and transplanting machine is a kind of logistics equipment, which is mainly used to change the conveying direction of items on the conveyor. It can lift and transplant items from one conveyor line to another, or send items from a branch line to or from the main conveyor line, so as to achieve smooth transfer of items between different conveyor lines. This equipment has a wide range of applications in the fields of industrial automation and logistics. A lifting and transplanting machine usually consists of two parts: a lifting mechanism and a transplanting mechanism. The lifting mechanism is responsible for lifting the items from the original position to a certain height, while the transplanting mechanism is responsible for moving the items from the lifting position to the target position. The coordinated work of these two mechanisms enables the items to be smoothly turned and transplanted during the transportation process.

[0004] Most traditional jacking transplanters use cylinders as the jacking power, however, this design does have several significant disadvantages. First, the use of cylinders requires a stable air source on site. This means that in addition to the cylinders themselves, additional air source equipment such as air compressors or gas cylinders is required. This not only increases the initial investment and operating costs of the equipment, but also makes the layout and installation of the equipment more complicated. Secondly, the cylinder needs to withstand huge forces during the jacking process. Since the working principle of the cylinder is to generate power through the compression and release of gas, the cylinder will be subjected to great pressure when jacking heavy objects. Being subjected to such pressure for a long time will not only affect the service life of the cylinder, but may also increase the risk of cylinder damage, thereby increasing maintenance costs.

[0005] The failure of the cylinder may cause the entire transplanter to shut down. Since the cylinder is a key component of the jacking and transplanting machine, once a failure occurs, the entire equipment may not work properly. This will not only affect production efficiency, but may also cause interruptions to the production line, causing significant losses to the company. In summary, although the traditional jacking and transplanting machine powered by a cylinder can meet production needs to a certain extent, its shortcomings cannot be ignored. Therefore, a more stable, more reliable and lower-cost jacking power method is sought. For this purpose, the utility model has developed a jacking and transferring device and a conveyor line. By twisting the motor on the jacking and transferring device, the goods are transported to the conveyor line in other directions. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The technical solutions provided by the various embodiments of the utility model are described in detail below in combination with the drawings.

[0034] See also Figures 1 to 4In the first aspect, the utility model provides a lifting and loading device, including a base 1, an upper beam 2 and a driving assembly 6; the upper beam 2 is provided with screw holes for installing other results, and the upper beam 2 can be used to install other structural equipment

[0035] The upper crossbeam 2 is installed on the top of the base 1, and an oil-free bushing 5 and a guide shaft 9 are installed at the connection between the upper crossbeam 2 and the base 1, and the oil-free bushing 5 is connected to the guide shaft 9;

[0036] Oil-free bushings and guide shafts can often be used together to build a smooth and low-friction linear motion system. The following are the basic steps of how oil-free bushings and guide shafts are used together:

[0037] Select and install the guide shaft: Select the appropriate guide shaft according to the application requirements. This is usually based on load capacity, accuracy requirements and the environment in which it is used. Fix the guide shaft in the appropriate position in the mechanical system. This usually involves the use of brackets, clamps or other mechanical devices to ensure the stability and accuracy of the guide shaft.

[0038] Select and install the oil-free bushing: Select the oil-free bushing that matches the guide shaft. The inner diameter of the oil-free bushing should match the outer diameter of the guide shaft to ensure smooth sliding. Install the oil-free bushing on the part that needs to slide, such as a slider or a moving platform.

[0039] Assembly and commissioning: Assemble the sliding parts with oil-free bushings onto the guide shafts, and ensure that the oil-free bushings can slide freely along the guide shafts without significant resistance. Perform necessary commissioning to ensure that all parts are assembled correctly, move smoothly, and have no jamming or excessive friction.

[0040] Test and Verify: Test the entire system under actual load conditions to verify its motion smoothness, accuracy and durability. Make necessary adjustments based on the test results, such as adjusting the preload, replacing more suitable oil-free bushings or guide shafts, etc.

[0041] Maintenance and Care: Although oil-free bushings do not require additional lubrication, they still need to be checked regularly for wear and replaced as needed. Regularly check the straightness and surface condition of the guide shaft to ensure that it remains in good working condition.

[0042] Optimization and Upgrade: Based on the performance in the actual application, you can consider optimizing or upgrading the system, such as replacing a higher-grade oil-free bushing to improve wear resistance and service life, or using a higher-precision guide shaft to improve motion accuracy.

[0043] Overall, the combination of oil-free bushings and guide shafts can provide a smooth, low-friction linear motion solution for mechanical systems.

[0044] A roller conveyor bracket 10 is installed on the top of the oil-free bushing 5 , and the driving assembly 6 is installed on the inner wall of the base 1 .

[0045] The side wall of the roller conveyor support 10 is installed with a lifting support 8 and a photoelectric component 4, and a needle bearing 11 is installed at the connection between the lifting support 8 and the driving component 6, and the driving component 6 is used to drive the needle bearing 11 to rotate;

[0046] The photoelectric component 4 establishes a communication connection with the drive component 6, and the photoelectric component 4 is used to control the start or shut down of the drive component 6. The technical solution of the present application can also install a control device on the base 1, and the control device is connected to the electrical components in the technical solution of the present application, wherein the control device establishes a communication connection with the photoelectric component 4, the roller conveyor 3 and the drive component 6. After the goods move to the vicinity of the photoelectric component 4, the photoelectric component 4 transmits the collected signal to the control device, and the control device starts the drive component 6 after receiving the signal transmitted by the photoelectric component 4, and the drive component 6 drives the needle bearing 11 to rotate. When the goods are lifted, the goods are not near the photoelectric component 4, and the photoelectric component 4 has no signal transmitted to the control device, and the control device shuts down the operation of the drive component 6. After receiving the shutdown command, the drive component 6 returns to its original position, thereby driving the needle bearing 11 to return to its original position, and the roller conveyor bracket 10 is lowered to the initial position. The technical solution of the present application can also directly connect the photoelectric component 4 with the drive component 6, and control the drive component 6 through the photoelectric component 4.

[0047] Specifically, the driving assembly 6 includes a driver 601, a transmission belt 602, a transmission rod 603 and a transmission gear set 604. The transmission gear set 604 is installed on the driver 601. One side of the transmission belt 602 is connected to the transmission gear set 604, and the other side of the transmission belt 602 is connected to the transmission rod 603. The transmission rod 603 is used to drive the needle bearing 11 to rotate.

[0048] The application of needle roller bearings in cargo lifting is mainly reflected in their ability to withstand high loads and provide stable support, especially in occasions with limited space. The following is a detailed explanation of how needle roller bearings are used for cargo lifting:

[0049] Characteristics of needle roller bearings 11: Although the cross-section of needle roller bearings is small, they have a high load bearing capacity. The rollers are thin and long, making them compact in radial structure, especially suitable for support structures with limited radial mounting dimensions. Needle roller bearings are suitable for precision instruments and equipment, providing stable support and ensuring high-precision operation of equipment. They can also work stably in corrosive environments and are suitable for a variety of industrial environments.

[0050] Needle roller bearings 11 are used in cargo lifting; Needle roller bearings can be used in cargo support and lifting mechanisms, such as cranes, elevators, etc. In these devices, needle roller bearings can withstand high loads and ensure smooth lifting of cargo. Because needle roller bearings are compact and take up little space, they can provide effective support and rotation functions in space-constrained occasions such as small cargo lifting platforms or compact material handling systems. During the cargo lifting process, needle roller bearings can provide stable support, reduce the impact of vibration and impact on the cargo, and ensure the accuracy and safety of lifting.

[0051] Specifically, a supporting foot cup 7 is installed at the bottom of the base 1 , and the guide shaft 9 is located vertically directly above the supporting foot cup 7 . The guide shaft 9 is vertically above the supporting foot cup 7 .

[0052] Specifically, the lifting support 8 includes a support plate 801, a rectangular through hole 802 and an arc-shaped through hole 803. The support plate 801 is provided with a long strip through hole, the arc-shaped through holes 803 are provided on both sides of the long strip through hole, and the rectangular through hole 802 is provided in the middle of the long strip through hole.

[0053] Specifically, the driving assembly 6 is located vertically below the needle bearing 11. The driving assembly 6 is used to provide driving force to the needle bearing 11. The driving assembly 6 is located below the needle bearing 11 to save space and reduce the force transmission distance.

[0054] Specifically, the angle between the oil-free bushing 5 and the roller conveyor support 10 is a right angle. The right angle design can keep the roller conveyor support 10 in a stable state during the rising process, reduce the shaking of the roller conveyor support 10, and indirectly reduce the shaking of the goods.

[0055] Specifically, the moving range of the needle bearing 11 on the lifting support 8 is limited between the rectangular through hole 802 and the arc through hole 803. The rotating part of the needle bearing 11 can slide in the arc through hole 803 and the rectangular through hole 802, so the design of the arc through hole 803 and the rectangular through hole 802 is adopted.

[0056] Specifically, the contact portion between the needle bearing 11 and the lifting support 8 is configured to be circular and matches the inner wall profile of the rectangular through hole 802 .

[0057] Specifically, a transmission rod connector is installed at the connection position between the transmission rod 603 and the transmission belt 602, and the transmission belt 602 drives the transmission rod connector to rotate, thereby indirectly driving the transmission rod 603 to rotate. The transmission rod connector can be a gear or other transmission connection components.

[0058] Specifically, the transmission belt 602 is configured as a transmission sprocket or a multi-V belt, and the transmission belt 602 is driven by the transmission gear set 604 .

[0059] In a second aspect, a conveyor line, a lifting and transferring device is applied to the conveyor line, comprising a lifting and transferring device and a cargo transport device, wherein the cargo transport device is connected to the lifting and transferring device, and the cargo transport device extends along a conveying direction and is used to transport cargo to the lifting and transferring device;

[0060] A roller conveyor 3 is installed on the roller conveyor bracket 10 in the lifting and transferring device. After the photoelectric component 4 in the lifting and transferring device detects that the goods are located on the roller conveyor 3, the lifting and transferring device pushes the goods upward, and then the roller conveyor 3 in the lifting and transferring device rotates to transport the goods to the conveying line in other directions.

[0061] See also Figure 7 , the rollers on the conveyor line rotate, and the goods can only move along the direction of the conveyor line. When reversing is required, the goods are moved above the lifting and transferring device, the lifting and transferring device is lifted, and the items on the conveyor line are lifted a little higher, and then the roller conveyor 3 on the lifting and transferring device runs to transport the goods to the conveyor line in other directions.

[0062] When the lifting and transferring device is lifted, the roller conveyor 3 on the top of the lifting and transferring device extends out from the gaps between the rollers on the conveyor line. When the lifting and transferring device is lowered, the roller conveyor 3 on the top of the lifting and transferring device is retracted from between the rollers on the conveyor line.

[0063] The utility model provides a lifting and transferring device and a conveying line. The process steps in the actual application scenario are as follows; the specific scenario is used to change the conveying direction of the items, and to send the items from the branch to or out of the main conveying line. For details, see Figure 7 .

[0064] First, see Figure 5 , Figure 6 as well as Figure 7 The cargo is transported from the X-axis direction to the top of the lifting and transplanting machine through the conveying device A. The lifting and transplanting machine controls the stop position through the photoelectric component. The cargo can be a material box or a pallet. The conveying device A can be a chain conveyor, a roller conveyor or other equipment.

[0065] Secondly, the lifting and transplanting machine lifts the goods; the specific process of the lifting and transplanting machine lifting the goods is that after the goods arrive near the photoelectric component 4, the photoelectric component 4 starts the driving component 6, the driver 601 in the driving component 6 drives the transmission gear set 604 to rotate, the transmission gear set 604 drives the transmission belt 602 to rotate, the transmission belt 602 drives the transmission rod 603 to rotate, the transmission rod 603 drives the needle bearing 11 to rotate, the needle bearing 11 is rotating, the lifting support 8 provides support force for the needle bearing 11 during the rotation process, the needle bearing 11 transmits the support force to the transmission rod 603 and generates an upward force, the oil-free bushing 5 and the guide shaft 9 push the roller conveyor bracket 10 upward.

[0066] Finally, the roller conveyor 3 above the transplanter operates to move the goods to above the conveying device B, thereby realizing vertical transfer of the goods.

[0067] The technical solution of the present application adopts a design method of mechanical force transmission, and does not use a method of lifting goods with a cylinder, thereby avoiding the problem that the existing jacking and transplanting machines use cylinders or cams to lift goods, and the cylinders will bear a lot of force when lifting up and down during the cargo lifting process, which affects the service life of the cylinders. The technical solution of the present application indirectly extends the service life of the jacking and transplanting machine.
